CAR-STQVE.

SPECIFICATION forming part of Letters Patent No. 385,491, dated July 3,1888.

Serial No. 245,436. (No model.)

To all whom it may concern:

Be it known that I, \VILLIAM PIATI' WHEELER, of Louisville, in thecounty of Jefferson and State of Kentucky, have invented a new andImproved Gar-Stove, of

which the following is a specification, reference being had to theannexed drawings, forming a part thereof, in which Figure 1 is avertical section of my improved IO carstove, taken on line as w in Fig.2. Fig. 2 is a horizontal section taken on line i 3 in Fig. 1, and Fig.3 is a horizontal section taken on line .2 a in Fig. 1.

Similar letters of reference indicate corresponding parts in all thefigures.

The object of my invention is to construct a stove for heatingrailway-cars, provided with appliances for extinguishing the fire incase of accidents or of the extraordinary tip ping, of the car.

My invention consists in the combination, with the stove, ofwater-reservoirs arranged above and around the stove and communicat ingwith the fire-pot of the stove through a p pipe provided with siphons,by which the upper reservoir is emptied when the car tips sufticientlyto set one or more of the siphons in operation,

It also consists in the combination, with the reservoir connected withthe siphons, of an auxiliary reservoir arranged to discharge into theupper reservoir in case of the unusual tipping of the stove.

It also further consists in the combination, with the reservoirs, ofdevices for preventing the surging of the water while the stove is inits normal condition.

Upon the fixed base-plate A, and held in place by its outer rim, rests,unfastened upon 0 its downwardextending rim I), the bottom plate of thestove, a. Tubes 0 pass through the plate a and through the car-floor,and are provided at their upper ends with strainers g. In annularconcentric grooves on the upper 5 side of the plate a are erected thecurved plates 0 and e, which are held in place between the entireannular coverfand the plate a by the short bolts d and by the long boltsJ. Within and between the two curved plates 0 and e is placed theannular reservoir B. This reservoir is divided perpendicularly by radialperforated partitions P and horizontally by perforated shelves Q. To thebottom of the reservoir are secured pipes a and stop'cocks j fordrainage, when desirable. Between the reservoir B and the plates 6, c,and a is placed heat-insulating materiahf A try-cock, T, is placed toshow the proper water-level in the reservoir B. Tubes I, open at bothends and secured water-tight at the bottom to the ms ervoir, inclose thelong bolts J. Access is obtained to the ash-receptacle and for stirringthe fire by a tunnel, b and tubes G, extending through the plates 0 andc and the reser voir B.

Between the upper part of the reservoir B and the fire-pot of the stovecommunication is opened through the short tubes 0. Over the mouth ofeach tube 0 is hung an automatic valve, 19, which is capable of openingby a 0 slight pressure of water and of closing by its own gravity. Thewater-reservoir B protects the surrounding materials from contact withthe pot of the stove. The air heated in the inclosed annular chamber Bis carried up Ward and outward over the coverf by air drawn through theholes 9 in the stovebase D and through the tubes 0.

To prevent lateral oscillation of the stove rings 0 surround the pipes 0between the So curved plates 0 and the body ofthe stove E, and serve tohold both in their proper relative position.

The upper part of the stove E, above the cover f,is surrounded by aperforated screen, s, which prevents the contact of combustiblematerials with the upper part of the stove.

The stove is made in sections, the combustion-chamber being formed ofupper and lower sections, E E contracted at their adjacent o ends, andconnected by a grooved ring, E while the lower edge of the section E isconnected with the fire-pot section by a grooved ring, 13*, having anannular groove, E in its upper surface outside of the section E The 5section E has an annular groove, E, in an outward-projecting part of itsupper end,and the cylindrical section 8 is firmly held in said annulargrooves by the bolts which connect the stove and reservoir together, andthe screen rco thereby becomes an integral part of the stove movablewith it.

To the conical top if of the stove is fitted a l1eat-insulatingcovering, u, and the annular space a between the insulating-covering aand the outer wall of the stove communicates with the external airthrough openings in, formed in the wall of the stove. The top of theannularspaee o is closed by a heat-insulating covering, a.

To the top of the stove-wall is fitted a ring, I), which supports anannular water-reservoir, H. The bottom of the water-reservoir H isformed of the plate 0, provided with the rim (2' around its periphery,and with a collar, 6, at its center corresponding in size with theopening of the stove-top t. The top of the annular reservoir H consistsof a plate, f grooved to receive the hoop 9 forming the sides ofthereservoir, and provided with down wardly projecting loose collars h h.The hoop g is inserted in the groove of the plate f and within the rim(1 of the bottom 0, and the collars h h are connected by the pipes t" j,the pipe 1" being placed within the collars and the pipe j outside ofthe collars. The space between the inner and outer pipes, tj, is filledwith a body, is, of heat-insulating material, which prevents thecommunication of heat to the water contained by the reservoir H. Thespace within the apertured ring I) forms a cold-air chamber, which, asit is thou oughly protected by non-eonducting material, a a, effectuallyprotects the bottom of the res ervoir H from becoming heated.

PipesIconimunicatewith the reservoirBand with the pipes 0, and extendupward through the bottom of the reservoir Hto the top thereof, and theupper end of each pipe is provided with perforations 1, about equalingin area the area of the pipe. A pipe, .I, of larger diameter than thepipe I, surrounds each pipe I between the top f and the bottom 0, and isprovided with perforations m at its lower end. The annular space betweenthe upper end of the pipe I and the pipe J,inclosing said pipe, is aboutequal in area to the area of the pipe I. Each pipe I, with itsinclosing-pipe J, forms a siphon adapted to draw water from thereservoir H whenever it is set in operation, in the manner presently tobe described, and to deliver it to the fire-pot of the stove.

Thereservoir B, the stove E, and the reservoir H are securely boundtogether by the long bolts J, extending through the said parts and'inelosed by the pipes I. The upper ends of the said bolts are threadedand provided with nuts 0, which may be made ornamental or not, accordingto requirements. Between the nuts 0 and the upper plate, f arecreceivedplates 17, which are secured to the Walls of the earand serve to preventthe displacement of the stove ordinarily v Upon the reservoir H ismounted an auxiliary annular reservoir, K, which communicates with thereservoir-H by pipes r, projecting downward through the top of thereservoir H and upward to the auxiliary reservoir K above thewater-level.

The inner wall of the annular reservoir K is made double, and theannular space inclosed by the wallsis filled with heat-insulatingmaterial. To the auxiliary reservoir K is fitted an inset top, S,provided with a perforated portion, s, through which the reservoir maybe filled with water.

The reservoirs K H are each provided with a wave-arrester, IJ, forpreventing the undue movement of the water contained by the saidreservoirs when the stove is in its normal con dition. Eachwave-arrester consists of a set of perforated disks, 25, connected byconcentric hoops a, and the spaces between the hoops are divided byradial partitions o. The area of all the perforations of each plate 25is in eX- cess of the area of one of the pipes I, so that when water isdrawn from the reservoir through the said pipe it may be freely suppliedthrough the perforations of the wavearresters.

The wave-arresters constructed in accordance with my invention areseparate and independent of the reservoirs and extend below thewaterline. The partitions a, being imperforate, prevent the water fromcircling, and the horizontal perforated disks, one above the other,break the upward force of the water and limit its movement withoutpreventing a free inflow.

The reservoir H is provided with try-cocks w, arranged at differentheights to determine the level of the water in the reservoir, and isalso provided with a glass water-gage, a of ordinary construction, forshowing the height of the water in the reservoir, and the lower parts ofthe reservoirs K H communicate with one of the pipes I through a branchpipe, b*, provided with valves 0".

The smoke and products of combustion pass from the stove E upwardthrough the annular reservoirs H K, and the heat of the the is preventedfrom being transmitted to the water in the reservoirs by the interveninginsulating material, and the insulating material surrounding thereservoir B and placed below it also protects the water in the saidreservoir B from freezing and from heat.

So long as the floor of the car which supports the stove maintains anapproximately level position the water is retained in the reservoirs andthe stove operates normally; but when the car is derailed or undulyinclined to one side or one end the water in the reservoir H flowsthrough the openings Z of the pipe I, starting the siphons and causingthe water to be discharged from the reservoir H through the said pipe Iand through the pipe 0 into the fire-pot of the stove, and the tippingof the reservoir K causes the water to flow over one of the pipes r toreplenish the reservoir H. The water discharged into the fire-pot afterflooding the-ash-receptacle G overflows, and is ICO IIO

discharged through the strainers g and pipes 0 through the floor of thecar.

When the water becomes exhausted in the reservoirs H and B byevaporation or otherwise, it is replenished from the reservoir K byopening the valve 0 and allowing the water to flow into the saidreservoir.

The valves p prevent dust and ashes from entering the pipes I throughthe pipes 0, but are capable of opening freely when pressed by water inthe pipes I 0. Should the car beinverted the water in the lowerreservoir, B, will be discharged into the fire.

In carrying out my invention I do not limit or confine my invention toany particular form of stove nor to any fiXed arrangement of pipes, asthese may be varied to adapt the devices to the requirements under whichthey are used.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1.
